BACKGROUND OF THE INVENTION Field of the invention This invention is directed to new organic compounds and is particularly concerned wtih novel l-aminoalkyl- 2,'2-disubstituted indolin-3-ones, and a process for the production thereof.

SUMMARY OF THE INVENTION The novel compounds and the process of production therefor can be illustratively represented as follows.

( zlr-Nmah III I wherein X is selected from the group consisting of hydrogen, alkyl of 1 to 3 carbon atoms, inclusive, halogen and CF R and R are selected from the group consisting of alkyl, defined as above, and C H X' in which X is selected from the group consisting of hydrogen, alkyl defined as above, alkoxy of l to 3 carbon atoms, inclusive, halogen and -CF wherein R is alkyl defined as "Ice above, or, together, the group N(R is selected from the group consisting of l-pyrrolidinyl, l-piperidinyl and 4- morpholinyl; and wherein n is an integer from 2 to 4, inclusive.

The process of the invention comprises: treating a 2,3- disubstituted-3H-indol-3-ol (I) with a stronge base to give the 2,2-disubstituted-3-indolinone (II); and treating the 3-indoline one (II) with sodium hydride and a haloamine of the Formula IV:

z)n s)2 wherein X" is chlorine or bromine, and n, R and -N(R are defined as herein described above, to give the N-alkylated 3-indolinone (III). Alternatively treating the indolol (I) with sodium hydride and subsequently with the halomine (IV) gives the corresponding substituted indolinone (III).

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of alkyl groups containing from 1 to 3 carbon atoms, inclusive, are methyl, ethyl, propyl and isopropyl.

Examples of alkoxy groups containing from 1 to 3 carbon atoms, inclusive, are methoxy, ethoxy, propoxy and isopropoxy.

The present invention also embraces the organic and inorganic acid addition salts of the novel amino compounds of Formula III particularly the pharmacologically acceptable acid addition salts such as the hydrochlorides, hydrobromides, hydroiodides, sulfates, cyclohexanesulfamates, acetates, propionates, laurates, palmitates, maleates, tartrates, lactates, citrates, as well as other salts, e.g., oxalates, perchlorates, fiuosilicates, thiocyanates, trifluoroacetates, trichloroacetates and the like.

The novel compounds of Formula III and the pharmacologically acceptable acid addition salts thereof have sedative and anticonvulsant activity.

Sedative effects were measured by the Chimney test [Med. Exp. 4, 11 (1961)]; the Dish test and the Pedestal test.

Chimney test: The effective intraperitoneal dosage for 50% of mice (ED is measured in mg./kg. The test determines the ability of mice to back up and out of a vertical glass cylinder within 30 seconds. At the effective dosage, 50% of the mice failed doing it.

Dish test; Mice in Petri dishes (10 cm. diameter, 5 cm. high, partially embedded in wood shavings) climb out in a very short time when not treated. When mice remain in the dish for more than 3 minutes, it indicates tranquilization. ED in mg./kg. (intraperitoneal administration) equals the dose of test compound at which 50% of the mice remain in the dish.

Pedestal test: The untreated mouse leaves the pedestal in less than a minute to climb back to the floor of the standard mouse box. Tranquilized mice will stay more than 1 minute. ED (intraperitoneal administration) is measured in m g/kg.

Anticonvulsive activity is determined by the Nicotine antagonism test. Mice in groups of-6 are injected intraperitoneally With the test substance. Thirty minutes later the mice, including control (untreated) mice, are injected with 2 mg./kg. of nicotine salicylate. The control mice show overstimulation, i.e., (1) running convulsions followed by (2) tonic extensor fits; followed by (3) death.

3 The ED (in mg./kg.) is the effective dosage at which the mouse is protected against (1), (2) or (3).

For carrying out the process of the present invention a selected 3H-indol-3-ol (I) in an organic solvent is ad- R E S U LT 5 50 a-I e) CH Dish Ped.

The pharmaceutical forms of compounds III contemplated by this invention include pharmaceutical compositions suited for oral, parenteral and rectal use, e.g., tablets, oils, powder packets, cachets, dragees, capsules, solutions, suspensions, sterile injectable forms, suppositories, bougies, and the like. Suitable diluents or carriers such as carbohydrates (lactose), proteins, lipids calcium phosphate, cornstarch, stearic acid, methylcellulose and the like may be used as carriers or for coating purposes. Oil, e.g., coconut oil, sesame oil, safflower oil, cottonseed oil, peanut oil may be used to prepare solutions or suspensions of the active drug. Sweetening, coloring and flavoring agents may be added.

For mammals and birds food premixes, with starch, oatmeal, dried fishmeat, fishmeal flour and the like can be prepared.

As tranquilizer the compounds of Formula III and the pharmacologically acceptable acid addition salts thereof can be used in dosages of 1 mg.-100 mg./kg. in oral or injectable preparations as described above, to alleviate tension and anxiety in mammals or birds, such as e.g., occurs when animals are in travel.

Other acid addition salts of the compounds of Formula III can be made such as the fluosilicic acid addition salts which are useful mothproofing compounds or the trichloroacetates useful as herbicides against Johnson grass, Bermuda grass, yellow foxtail and green foxtail, and quack grass.

Some of the starting materials I of this invention have been described in the literature. Others can be made from an aminobenzophenone or aminoacetophenone (A). The process consists of acylating the amino group of (A) with an acyl chloride to obtain the corresponding amide (B), to reduce (B), e.g., with sodium borohydride to obtain the corresponding a-hydroxy a substituted-o-toluidide (C), to cyclize (C) with hydrogen bromide or sulfuric acid to obtain the benzoxazine (D); to produce the novel ring contraction of (D) in liquid ammonia with sodium amide to give the compound of Formula I. These reactions can be illustratively represented as follows:

1 Lou X I wherein X, R, and R are defined as above.

test; Ped.=Pedestal test; Nic=Nieotine antagonism-(1) running convulsions mixed with a base dissolved in water. The solvent is an organic, water-miscible solvent, unreactive under the experimental conditions. Alkanols, e.g. methanol ethanol, l-propanol, 2-propanol, t-butyl alcohol and the like, tetrahydrofuran, and the like are useful solvents. The base is generally sodium or potassium hydroxide dissolved in water. In the preferred embodiment of this reaction, methanol or ethanol is used as solvent; about 0.3 to 2 times of weight of sodium or potassium hydroxide is used compared to the weight of starting material; and the mixture is heated to reflux for 1 to 12 hours. The reaction is operative at temperatures between 40 to 80 C. At the termination of the reaction the mixture is evaporated in vacuo, and the residue suspended in added water is collected on a filter. The thus-obtained product, a 2,2-disubstituted-3-indolinone (II), is purified in conventional manner, e.g., by recrystallization from organic solvents such as ether, methanol, ethanol, ethyl acetate, methylene chloride and the like.

The thus-obtained 3H-indolinone (II) is N-alkylated with sodium hydride and a haloamine compound of the Formula IV wherein X n and R are defined as hereinabove, is added. In the preferred embodiment of this invention the sodium hydride is added in an excess of 5 to 100% of the stoichiometrically required amount and is conveniently used in suspension in mineral oil (56% of NaH) as commercially available. The reaction is carried out in an organic, inert solvent, e.g., dialkyl acid amides such as dimethylformamide, diethylformamide, dirnethylacetamide and toluene, benzene, cyclohexane or the like, usually at a temperature between 10 and C. After permitting the reaction mixture to stand from 1 to 30 minutes, the haloamine (IV) of the above formula is added, and the reaction mixture is heated for 2 to 48 hours at reflux. Temperatures between 40 C. and the reflux temperature are operative. Following the termination of the reaction the product is isolated by conventional measures, such as evaporating the solvent or extracting the product and then purifying it by crystallization and recrystallization, often in the form of an acid addition salt such as the hydrochloride, to obtain the compound of Formula III.

Alternatively, the above reaction, i.e., treatment with sodium hydride in dialkylformamide and a hydrocarbon such as benzene toluene, cyclohexane and the like and subsequently with a haloamine (IV) as above can also be carried out with compound (I) to give in one step a compound of Formula III.
